RICOH RP901K Series PWM/VFM Step-down DC/DC Converter with Synchronous Rectifier Equipped with VR VD handbook
The RP901K Series are CMOS-based PWM/VFM step-down DC/DC converters equipped with voltage regulator and voltage detector. The DC/DC converter can be selected from two control types - fixed PWM control or PWM/VFM auto switching control in which mode automatically switches to high-efficiency VFM mode in low output current. RP901K was developed for applications that require multiple power supplies such as storage devices. It integrates an 800mA output current step-down DC/DC converter, a 600mA output current LDO regulator, and a voltage detector with a built-in delay circuit into a small package. The regulator can be started after soft start of the DC/DC converter by sequence control.
